[0020] By adopting the above technical solution, the patient's body is scanned by the scanner 102, and then the scanned image is transmitted to the imaging module 103, and the imaging module 103 displays the scanned image, and the imaging module 103 transmits the image data to the data processing module 104 for processing, wherein the patient's breathing can be monitored by the chest motion sensor 105, and the patient's breathing data is transmitted to the data processing module 104, and the data processing module 104 compares the patient's breathing information with the image information transmitted by the imaging module 103 to determine the position and size change of the tumor during the patient's breathing process, and specifically realizes the positioning of the tumor contour information through the following code: import cv2 import numpy as np img = cv2.imread("tumor_image.png", cv2.IMREAD_GRAYSCALE) if img is None: print("Error: Could not load image.") else: ret, thresh = cv2.threshold(img, 127, 255, cv2.THRESH_BINARY) contours, hierarchy = cv2.findContours(thresh, cv2.RETR_EXTERNAL,cv2.CHAIN_APPROX_SIMPLE) if contours: largest_contour = max(contours, key=cv2.contourArea) epsilon = 0.01 * cv2.arcLength(largest_contour, True) approx = cv2.approxPolyDP(largest_contour, epsilon, True) cv2.drawContours(img, [approx], -1, (0, 255, 0), 3) cv2.imshow("Tumor Contour", img) cv2.waitKey(0) cv2.destroyAllWindows() else: print("Error: No contours found."); The location of the tumor is located through the following code: import cv2 import numpy as np def find_tumor_location(image_path, threshold_value=127): """ Finds the approximate location of a tumor in a grayscale image using thresholding.

[0021] An electric slide rail 2 is fixedly mounted on the fixed cover 1, and two sliders 201 are mounted inside the electric slide rail 2. A simulation positioning machine 202 is mounted on the lower side of one of the sliders 201. The simulation positioning machine 202 can simulate a radiation generating device 203, so as to conduct a simulated treatment experiment, repeatedly simulate and obtain the optimal surgical process, so that the radiation generating device 203 is more accurate during treatment. The simulation positioning machine 202 can use X-rays for simulation, and a radiation generating device 203 is mounted on the lower side of the other slider 201. The radiation generating device 203 can work using a linear accelerator or a gamma knife. The lower ends of the two sliders 201 are both embedded with rotating balls 204, and the lower ends of the two rotating balls 204 are fixedly connected to the upper ends of the simulation positioning machine 202 and the radiation generating device 203 respectively; Two first friction wheels 205 for driving the rotating ball 204 to rotate are embedded inside the slider 201 corresponding to the simulation positioning machine 202, and the two first friction wheels 205 are oriented perpendicular to each other. The outer walls of the first friction wheels 205 are in friction contact with the outer walls of the rotating ball 204. A first servo motor 206 for driving the first friction wheel 205 to rotate is installed on one side of the first friction wheel 205, and a first motor rotary encoder 207 is installed on the first servo motor 206.

[0022] By adopting the above technical solution, the slider 201 equipped with the simulation positioning machine 202 can be adjusted to a suitable position through the electric slide rail 2. Afterwards, when the data processing module 104 detects that the tumor is at its maximum or minimum, the simulation positioning machine 202 is used to perform a simulated radiotherapy experiment. When the simulation positioning machine 202 is working, the data processing module 104 will send different information to the control module 211 through different image information, thereby controlling the first servo motor 206 in the slider 201 corresponding to the simulation positioning machine 202 to work, thereby adjusting the angle of the rotating ball 204, so that the orientation of the simulation positioning machine 202 is different, so that the tumor size or position can be moved. When the simulation is completed, the X-ray of the simulation positioning machine 202 is always aimed at the location of the tumor. When the first servo motor 206 is working, the first motor rotary encoder 207 can record the rotation angle information of the first servo motor 206 each time. Then the first motor rotary encoder 207 transmits the recorded data to the data processing module 104 for recording. When the simulation is completed, the electric slide rail 2 is controlled to move the slider 201 with the simulation positioning machine 202 away, and the slider 201 with the radiation generating device 203 is moved to the initial position with the simulation positioning machine 202, so that the position of the radiation generating device 203 is the same as the position when the simulation positioning machine 202 is working.

[0023] The first motor rotary encoder 207 records the angle of each rotation of the first servo motor 206 , and the first motor rotary encoder 207 transmits the recorded rotation angle data of the first servo motor 206 to the data processing module 104 ; Two second friction wheels 208 for driving the rotating ball 204 to rotate are embedded inside the slider 201 corresponding to the radiation generating device 203, and the two second friction wheels 208 are oriented perpendicular to each other, and the outer walls of the second friction wheels 208 are in friction contact with the outer walls of the rotating ball 204. A second servo motor 209 for driving the second friction wheels 208 to rotate is installed on one side of the second friction wheel 208; The second servo motor 209 is provided with a second motor rotary encoder 210, which records the angle of each rotation of the second servo motor 209, and transmits the recorded rotation angle data of the second servo motor 209 to the data processing module 104; A control module 211 is fixedly installed on the outer wall of the electric slide rail 2. The data processing module 104 transmits the data processing result to the control module 211. The control module 211 controls the electric slide rail 2 to drive the slider 201 to move, and the control module 211 is used to control the first servo motor 206 and the second servo motor 209 to work. The first motor rotary encoder 207 and the second motor rotary encoder 210 can facilitate the second servo motor 209 to accurately simulate the working state of the simulation positioning machine 202 to ensure accuracy during the operation.

[0024] By adopting the above technical solution, when the position of the radiation generating device 203 is the same as the position when the simulation positioning machine 202 is working, the data processing module 104 controls the radiation generating device 203 to work when the imaging module 103 detects that the tumor is maximum or minimum. The start of this step needs to be the same as the state of the simulation positioning machine 202 at the beginning, and the data processing module 104 sends a signal to the control module 211 through the data transmitted by the first motor rotary encoder 207, and the control module 211 controls the second servo motor 209 to work, so that the second friction wheel 208 rotates to drive the radiation generating device 203, so that the direction of the radiation generating device 203 changes, thereby radiating the tumor position through the first motor rotary encoder 207.

[0025] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
